Power factor
Fire suppression for PFC panels
Power factor correction is vital for reducing costs, but the high density of capacitors and components in a PFC panel creates a significant fire risk. Dedicated in-panel fire suppression is not merely an option; it is a critical, life-saving investment that protects valuable electrical assets, keeps people safe, and secures uninterrupted business continuity.
- PFC panels pack many capacitors and components, which creates a real fire risk.
- Fires start from electrical faults or overloads, capacitor rupture, or dust and rodent ingress.
- In-panel fire suppression contains and extinguishes a fire at its source.
- It protects assets, keeps people safe, and secures business continuity.
Power factor correction improves the efficiency of electrical power use. By improving the power factor, PFC systems reduce maximum demand, lower utility costs and enhance the performance of the electrical infrastructure. But those benefits come with an inherent risk that is easy to overlook.
The inherent fire risk in PFC panels
PFC panels house numerous capacitors and reactive components that, if poorly installed, poorly maintained, or exposed to harmonics, can generate excess heat. Fires can start from:
- Electrical faults or overloads.
- Capacitor failure, leading to rupture and ignition.
- External issues such as dust accumulation or rodent ingress.
A fire within a panel can escalate rapidly, threatening the entire facility.
Why fire suppression is crucial
Dedicated suppression inside the panel enclosure is a critical strategy for asset integrity and operational resilience:
- Asset protection: a fire causes costly downtime and severe component damage. Suppression contains and extinguishes it at source, minimising the loss.
- Personnel safety: fires in energised panels are extremely hazardous; early-stage suppression protects the people nearby.
- Business continuity: stopping a fire before it spreads keeps operations running and protects the wider site.

Why do PFC panels catch fire?
They house numerous capacitors and reactive components that can generate excess heat if poorly installed, poorly maintained, or exposed to harmonics. Common causes include electrical faults or overloads, capacitor failure and rupture, and dust accumulation or rodent ingress.
Why is in-panel fire suppression important?
A fire in an energised panel escalates rapidly and is extremely hazardous. Dedicated suppression detects and extinguishes it at the source, minimising component damage, downtime and risk to personnel.
Is fire suppression only about safety?
It protects safety and the business. PFC panels are valuable assets, and a fire causes costly downtime and damage. Suppression protects the asset, the people and continuity of operations together.
